New methods of refractive-index determination
Author(s): Ludmila A. Gerasimova

Paper Abstract

ning is refractive index n We suggest new methods of refractive index determination which are absolute and realized without complicated ope— rations and equipment. New optical methods are used for non—destructi— ye control of optical materials with different shapes of surfaces. They don't require any information about samples to be controlled. The first new interference method of refractive index determination is used for transparent materials with varifom surface. In this case the order of interference depends on geometric co—ordinates. These equ— ations for passing and reflecting light are :
